1. Permitted facility description
The Bliss Collector Wastewater Treatment Facility (facility) is located at 18925 Manning Trail, Scandia, Minnesota 55073,
Washington County.
The facility discharges from WS 002 to land via drainfields. The facility is a Class D.
The facility is designed to treat effluent from approximately 75 homes. There are 70 individual septic tanks and
46 shared Septic Tank Effluent Pump (STEP) systems through which sewage passes before entering the collection
system:
• An average wet weather (AWW) flow of 0.0198 million gallons per day (mgd)
• 5-day carbonaceous biochemical oxygen demand (CBOD5) of 170 milligrams per liter (mg/L)
• total suspended solids (TSS) of 28 mg/L
This facility consists of small diameter force main, two lift stations, a stilling basin comprised of three septic tanks in
series (7,500 gallons total), a dosing station and three single pass-through sand filter beds, and a dosing station going to
a three-cell drainfield trench system. The drainfield system consists of three cells of drop box drainfields with ten laterals
each. One or two cells rest at any given time. There are no known bypass points in this system. There are four
monitoring wells at this site, one up gradient (GW 001) and three down gradient (GW 004, GW 006, and GW 008). This
permit includes a schedule to abandon GW 008 and replace with a new well (GW 018). There are also nine piezometers
(GW 009-GW 017).

Permit issued: September 1, 2021 MN0054119
Permit expires: August 31, 2026 Page 28 of 41
be permitted, nor shall a person commence an activity for which a permit is required by statute or
rule until the MPCA issues a written permit for the facility or activity.
Permittees that propose to make changes to the facility or discharge that requires permit
modification shall follow Minn. R. 7001.0190. If the Permittee cannot determine whether the
proposed changes require a permit modification, the Permittee shall contact the MPCA prior to any
action. The MPCA recommends that Permittees submit the application for permit modification to
the MPCA at least 180 days prior to the planned change. [Minn. R. 7001.0030]
5.26.167 This permit does not require plans, specifications, and MPCA approval when maintenance dictates
the need for installation of new equipment, provided the equipment is the same design size and has
the same design intent. For instance, Permittees can replace a broken pipe, lift station pump,
aerator, or blower with the same design-sized equipment without MPCA approval.
If this permit does not expressly authorize the Permittee proposed construction, the MPCA may
require a permit modification. If the proposed construction project requires an Environmental Assessment Worksheet under Minn. R. 4410, no construction shall begin until the MPCA issues a
negative declaration and the Permittee receives or implements all approvals. [Minn. R. 7001.0030]
5.26.168 Report Changes. The Permittee shall give advance notice as soon as possible to the MPCA of any
substantial changes in operational procedures, activities that may alter the nature or frequency of
the discharge, and/or material factors that may affect compliance with the conditions of this permit.
[Minn. R. 7001.0150, subp. 3(M)]
5.26.169 Chemical Additives. The Permittee shall receive prior written approval from the MPCA before
increasing the use of a chemical additive authorized by this permit, or using a chemical additive not
authorized by this permit, in quantities or concentrations that have the potential to change the
characteristics, nature, and/or quality of the discharge.
The Permittee shall request approval for an increase or new use of a chemical additive at least 60 days, or as soon as possible, before the proposed increase or new use. The Permittee shall include
at least the following information for the proposed additive as instructed in the chemical additive
approvals section on the MPCA website at https://www.pca.state.mn.us/water/wastewater-
additional-guidance-and-information:
A. The process for which the additive will be used; B. Safety Data Sheet (SDS) which shall include aquatic toxicity, human health, and environmental
fate information for the proposed additive. The aquatic toxicity information shall include at
minimum the results of: a) a 48-hour LC50 or EC50 acute study for a North American freshwater
planktonic crustacean (either Ceriodaphnia or Daphnia sp.) and b) a 96-hour LC50 acute study for
rainbow trout, bluegill, or fathead minnow or another North American freshwater aquatic species
other than a planktonic crustacean;
C. A complete product use and instruction label;
D. The commercial and chemical names and Chemical Abstract Survey (CAS) number for all
ingredients in the additive (If the SDS does not include information on chemical composition,
including percentages for each ingredient totaling to 100%, the Permittee shall contact the
supplier to have this information provided); and
E. The proposed method of application, application frequency, concentration, and daily average and
maximum rates of use.
Upon review of the information submitted regarding the proposed chemical additive, the MPCA may
require additional information be submitted for consideration. This permit may be modified to
restrict the use or discharge of a chemical additive and include additional influent and effluent
monitoring requirements. Approval for the use of an additive shall not justify the exceedance of any
effluent limitation nor shall it be used as a defense against pollutant levels in the discharge causing
or contributing to the violation of a water quality standard. [Minn. R. 7001.0170]
Permit issued: September 1, 2021 MN0054119
Permit expires: August 31, 2026 Page 29 of 41

of this permit pursuant to Minn. R. 7001.0180. [Minn. R. 7001.0170, Minn. R. 7001.0180]
5.26.171 Total Maximum Daily Load (TMDL) Impacts. The MPCA may require facilities that discharge to an
impaired surface water, watershed, or drainage basin to comply with additional permits or permit
requirements. These requirements can include additional restriction or relaxation of limits and
monitoring as authorized by the CWA 303(d)(4)(A) and 40 CFR ch. 122.44(l)(2)(i), necessary to ensure
consistency with the assumptions and requirements of any applicable EPA approved wasteload
allocations resulting from TMDL studies. [40 CFR 122.44(I)(2)i]
5.26.172 Permit Transfer. This permit is not transferable to any person without the express written approval
of the MPCA after compliance with the requirements of Minn. R. 7001.0190. A person who receives
permit transference shall comply with the conditions of this permit. [Minn. R. 7001.0150, subp. 3(N)]
5.26.173 Facility Closure. The Permittee is responsible for closure and post-closure care of the facility. The
Permittee shall notify the MPCA of a significant reduction or cessation of the activities described in
this permit at least 180 days before the reduction or cessation. The MPCA may require the Permittee
to provide a Facility Closure Plan to the MPCA for approval.
The MPCA may require a permit modification or reissuance for facility closure that could result in a
potential long-term water quality concern, such as the ongoing discharge of wastewater to surface
or groundwater.
The MPCA may require the Permittee to establish and maintain financial assurance to ensure performance of certain obligations under this permit, including closure, post-closure care, and
remedial action at the facility. If the MPCA requires financial assurance, the MPCA shall approve the
amount and type of financial assurance, and proposed modifications to previously MPCA-approved
financial assurance. [Minn. Stat. ch. 116.07, subd. 4]
5.26.174 Permit Reissuance. If the Permittee desires to continue permit coverage beyond the date of permit
expiration, the Permittee shall submit an application for permit reissuance: Due by 180 days prior to
permit expiration. [Minn. R. 7001.0040]
5.26.175 If the Permittee does not intend to continue the activities authorized by this permit after the
expiration date of this permit, the Permittee shall notify the MPCA in writing at least 180 days before
permit expiration. If the Permittee has submitted a timely application for permit reissuance, the
Permittee may continue to conduct the activities authorized by this permit, in compliance with the
requirements of this permit, until the MPCA takes final action on the application, unless the MPCA
determines any of the following:
A. The Permittee is not in substantial compliance with the requirements of this permit, or with a
stipulation agreement or compliance schedule designed to bring the Permittee into compliance
with this permit;
B. The MPCA, as a result of an action or failure to act by the Permittee, has been unable to take final action on the application on or before the expiration date of the permit; or
C. The Permittee has submitted an application with major deficiencies or has failed to properly
supplement the application in a timely manner after being informed of deficiencies.
